BACKGROUND

The present invention relates to a system for managing geographic space and mobile objects thereon.

A high-speed driving support and automobile system is known that receives information from a plurality of automobiles, acquires information concerning accidents or obstructions on the road and maps this information onto a map along with the position of an automobile, and references automobile position information, automobile characteristic information, and driver characteristic information to transmit suitable event information to each automobile.

However, such a system has a problem that as the geographic space being handled expands, the number of automobiles and the number of roads increases, thereby increasing the amount of information being sent and received to a level that surpasses the processing capability of the server. Furthermore, it is difficult to predict the actions of automobiles that do not communicate with this system, such as automobiles being driven manually and automobiles managed by other systems, and this is a cause for dangerous driving and accidents.

DETAILED DESCRIPTION

Hereinafter, example embodiments of the present invention will be described. The example embodiments shall not limit the invention according to the claims, and the combinations of the features described in the embodiments are not necessarily essential to the invention.

FIG. 1 shows a system 100 and a map area corresponding to a geographic space managed by the system 100, according to an embodiment of the present invention. The system 100 manages a geographic space that includes routes on which a mobile object 10 moves. The system 100 is operable to divide the geographic space into a plurality of regions and manage these regions. A mobile object 10 may move on routes including land routes, sea routes, and/or air routes, for example. The geographic space may be land, sea, or air space that includes the routes on which the mobile object travels. The mobile objects 10 may be manned/unmanned automobiles, motorbikes, bicycles, humans having a digital device, airplanes, vessels, drones, or the like.

FIG. 1 shows an automobile as an example of the mobile object 10, which moves along roads as examples of land routes. The system 100 includes a plurality of subsystems 200 that respectively manage the plurality of regions. FIG. 1 shows an example in which the map area is divided into six regions from region A to region F, and six subsystems 200 respectively manage these six regions.

System 100 comprises a plurality of event servers 210, a plurality of mobile object servers 220, a plurality of object servers 230, and a plurality of passenger servers 240. According to the embodiment of FIG. 1, each of the subsystems 200 may include at least one of the plurality of event servers 210 and one of the plurality of mobile object servers 220.

The event server 210 manages events occurring in each region of the geographic space. In one embodiment, the event server 210 of subsystem 200 assigned to region A may manage events in region A. The plurality of mobile object servers 220 respectively assigned to a plurality of regions in a geographic space manage the mobile objects 10 in each of the plurality of regions. In one embodiment, the mobile object server 220 assigned to region A may manages mobile objects 10 located in region A. The object server 230 manages information of the mobile objects 10 regardless of the location of the mobile objects 10. The passenger server 240 manages information of at least one passenger riding on the mobile objects 10.

Each of the subsystems 200 may be implemented on one or more servers. In one embodiment, each event server 210 and mobile object server 220 may be implemented on one server. In one embodiment, a set of an event server 210 and a mobile object server 220 in a subsystem 200 may be implemented by one server. Portions of the system 100 other than the subsystems 200 may also be implemented on one or more servers. In one embodiment, each object server 230 and passenger server 240 may be implemented on one server. In another embodiment, a set of object servers 230 and a set of passenger servers 240 may be each implemented by one server. In yet another embodiment, all of the object servers 230 and the passenger servers 240 may be implemented on one server. These servers may exist at any point on a network including the Internet, a subscriber network, a cellular network, or a desired combination of networks. The servers may be computers or other types of data processors, and may be dedicated servers, or may be shared servers that perform other operations.

The system 100 acquires the positions of a mobile object 10 from the mobile object 10, and the mobile object server 220 managing the region that includes the acquired position of the mobile object 10 may manage the movement of this mobile object 10. The system 100 acquires information of events that have occurred to the mobile object 10 and/or on the road outside, and the event server 210 managing the region including the position where such an event has occurred may manage the state of the event.

This event may include information about accidents, obstructions, closure, limitation, status, or construction on the road, or information about the weather, temperature, buildings, shops, or parking lots near the road. In response to a setting or a request from the mobile object 10, the subsystem 200 may provide notification about the event information to the mobile object 10 that made the request. For example, if the mobile object 10 is moving on a route in a geographical area corresponding to region A, then the mobile object sever 220 managing region A provides this mobile object 10 with the notification about the event relating to the route.

Since the map area is divided into a plurality of regions, despite the mobile object 10 simply moving on a route, the region corresponding to the position of the mobile object 10 might change. FIG. 1 shows an example in which the mobile object 10 is driving on a road such that the position of the mobile object 10 moves from region A to region B on the regions. In this case, according to the movement of the mobile object 10, the system 100 may transfer the information concerning the mobile object 10 from the mobile object server 220 managing region A to the mobile object server 220 managing region B, and may also transfer the management of the mobile object 10 to the mobile object server 220 managing region B.

FIG. 2 shows a subsystem 200 and a map area corresponding to a region A managed by the subsystem 200, according to an embodiment of the present invention. The event server 210 manages at least one event agent, and executes each event agent to manage events on routes in a region assigned to the event server 210. An “agent” may be a software entity having specific data, and may operable to receive a message (e.g. command), and return a result of the message. Each region of the plurality of regions of geographic space includes at least a portion of one area of the plurality of areas. In this embodiment, the region assigned to the event server 210 is the same as the region assigned to the mobile object server 220. However, in other embodiments, these regions may be different.

In the embodiment of FIG. 2, the region A, which is the region assigned to the event server 210, is divided into 16 areas and 16 areas are assigned to each of the event agents EA1-EA16. The event server 210 executes each of the event agents EA1-EA16 to manage events occurring on routes of each area of region A. For example, the event agent EA2 may manage a “closure” event on an area corresponding to EA2 on the map, and the event agent EA4 may manage a “speed limit” event on an area corresponding to EA4 as shown in FIG. 2.

The plurality of mobile object servers 220 may include at least one mobile object server 220 including one or more mobile object agents, each of which is assigned to each of the mobile objects 10. In the embodiment of FIG. 2, the mobile object server 220 includes three mobile object agents MOAs 1-3 assigned to three mobile objects 10 in the assigned region A. The mobile object server 220 executes each of the mobile object agents MOA1-MOA3 to manage the mobile objects 10 traveling on the region A.

FIG. 3 shows an exemplary configuration of the system 100, according to an embodiment of the present invention. The system 100 may be operable to communicate with each of a plurality of mobile objects 10 to send and receive the information used to manage the mobile objects 10.

The region manager 140 may be operable to specify the subsystem 200 managing the region that includes the position of the mobile object 10, in response to receiving the position of the mobile object 10. The region manager 140 may be implemented on one or more servers. The region manager 140 includes a storage section 142 and a determining section 146.

The storage section 142 may be operable to communicate with the dividing section 130 and store information concerning the plurality of first regions and the plurality of second regions resulting from the division by the dividing section 130. The storage section 142 may store setting values or the like of the system 100.

The storage section 142 may store intermediate data, calculation results, threshold values, parameters, and the like that are generated by or used in the operations of the system 100. In response to a request from any component within the system 100, the storage section 142 may supply the data stored therein to the component making the request. The storage section 142 may be a computer readable storage medium such as an electric storage device, a magnetic storage device, an optical storage device, an electromagnetic storage device, or a semiconductor storage device.

The determining section 146 may be operable to communicate with the storage section 142, and determine one region from the plurality of regions (e.g., regions A-F of FIG. 1) in which each of the mobile objects 10 is located based on the position information of the mobile object 10 and geographic information of the plurality of regions. The determining section 146 may identify a route or position in the map area managed by the system 100 that corresponds to the position information of the mobile object 10.

The determining section 146 may store the position information of this mobile object 10 and/or information of the determined region in the storage section 142, in association with this mobile object 10. The determining section 146 may store a history of the position information of this mobile object 10 and/or a history of the determined mobile object server 220 in the storage section 142. The determining section 146 may be a circuit, a shared or dedicated computer readable medium storing computer readable program instructions executable by a shared or dedicated processor, etc.

The receiving section 150 may be operable to receive information transmitted from each of a plurality of mobile objects 10. Each mobile object 10 may transmit information at designated time intervals, and the receiving section 150 may sequentially receive this transmitted information. In this embodiment, the receiving section 150 may receive car probe data from each mobile object 10 as the information. The car probe data may include information detected by the mobile object 10, such as position information of the mobile object 10.

In one embodiment, the position information may include longitude and latitude (and optionally altitude information) of the mobile object 10 in an absolute coordinate system. In another embodiment, the mobile object 10 may determine its location in the absolute coordinate system by using GPS, and the determining section 146 receiving the position information may determine a route on which the mobile object 10 exists and a specific location of the route at which the mobile object 10 exists based on the position information. Alternatively, the mobile object 10 may include such detailed position information in the car probe data.

The receiving section 150 may communicate with the plurality of mobile objects 10 and receive the car probe data of each mobile object 10, via the Internet 40. The receiving section 150 may receive the car probe data of the plurality of mobile objects 10 through wireless communication, a subscriber network, a cellular network, or any desired combination of networks.

The transmitting section 152 may be operable to transmit event information to each of the mobile objects 10 according to settings, for example. The transmitting section 152 may transmit information concerning the route on which the mobile object 10 is expected to travel. The transmitting section 152 may communicate with the mobile objects 10 and transmit each type of information to the mobile objects 10 via the Internet 40. The transmitting section 152 may transmit each type of information to the mobile objects 10 through wireless communication, a subscriber network, a cellular network, or any desired combination of networks.

The gateway apparatus 160 may be operable to transfer communication between the plurality of subsystems 200 and the plurality of mobile objects 10. The gateway apparatus 160 may communicate with the receiving section 150 and receive the information transmitted by each mobile object 10.

The gateway apparatus 160 may communicate with the region manager 140 and demand the transfer destination for each piece of information received from the mobile objects 10, of the region manager 140. In response to this request, the gateway apparatus 160 may receive from the region manager 140 the information of the subsystem 200 managing the region on which the mobile object 10 exists. The gateway apparatus 160 may transfer the information received from the mobile object 10 to the subsystem 200 that is to manage the mobile object 10. In other words, the gateway apparatus 160 may transfer the information received from each mobile object 10 to the subsystem 200 determined by the region manager 140.

The gateway apparatus 160 may communicate with each of the subsystems 200, and receive the information transmitted by each subsystem 200. The gateway apparatus 160 may communicate with the transmitting section 152 and supply the transmitting section 152 with the information received from each subsystem 200, such that this information is transferred to the mobile objects 10 designated for each subsystem 200.

The gateway apparatus 160 may include a plurality of gateway devices, and may quickly perform transfer between the plurality of subsystems 200 and the plurality of mobile objects 10. In this case, the receiving section 150 may function as a load balancer that supplies the information from the mobile objects 10, such that the load is spread among the plurality of gateways. The load balancer may sequentially supply information from the mobile objects 10 to the gateways having lighter loads. The gateway apparatus 160 may be a network that provides a connection between a plurality of networks using the same or different types of protocols.

A plurality of subsystems 200 may be operable to communicate with the region manager 140 and the gateway apparatus 160 and to respectively manage a plurality of regions in a geographic space. Each subsystem 200 is operable to manage mobile objects 10 that travel routes in its managing region and to manage events on its managing region.

As described, each subsystem 200 may include the event server 210 and the mobile object server 220. The event server 210 manages events occurring on its managing region with the plurality of the event agents. In one embodiment, the event server 210 may perform, through the event agent, (i) registration, update and/or deletion of events, (ii) registration, update and/or deletion of candidate events, and (iii) provision of event information.

The mobile object server 220 manages the plurality of the mobile objects 10 traveling on its managing region with the plurality of the mobile object agents. In one embodiment, the mobile object server 220 may perform, through the mobile object agent, (i) processing of the car probe data, (ii) update of information of the mobile object, and (iii) provision of information to the mobile object. For example, the mobile object server 220 may execute the mobile object agent to collect information of events from at least one event server 210, and provide the mobile object 10 with information that assists the mobile object 10 with traveling in the geographic space.

A plurality of object servers 230 including at least one object server 230 may communicate with the gate way 160 and include an object agent (OA) containing information of the mobile object 10. An object agent may correspond to each mobile object 10 and contain information thereof. In one embodiment, the object agent may contain (i) information, by region, of which subsystem currently manages a mobile object agent of the mobile object 10, (ii) an identification (ID) of the mobile object 10, (iii) an ID of a passenger of the mobile object 10, and (iv) a characteristic of the mobile object 10 (e.g., model/version information, width, length, and/or height of the mobile object 10).

The object server 230 may perform, through the object agent, (i) provision and/or update of information of the mobile object 10, (ii) registration, update, and/or deletion of the ID of passenger riding on the mobile object 10, (iii) provision and/or update of the information of the region of the mobile object 10, and (iv) provision of information needed for generation of a new mobile object agent by the mobile object server 220.

At least one passenger server 240 of a plurality of passenger servers may communicate with the gateway 160, and include a passenger agent that contains information of at least one passenger. A passenger agent may correspond to each passenger or candidate passenger of mobile objects 10, and contain information thereof. In one embodiment, the object agent may contain an ID of a passenger and a characteristic of the passenger (e.g., information of age, gender, type, and the like of license of the passenger). The passenger server 240 may perform, through the passenger agent, provision and/or update of information of the passengers.

As described above, the system 100 of the present embodiment may manage the mobile objects by utilizing the mobile object agents in each mobile object server 220, and manage the events by utilizing the event agent in each event server 210. According to the system 100 of the embodiment, the system 100 can separately manage information relating to the mobile objects 10 and events on the geographic map with a plurality of kinds of servers. Furthermore, the plurality of mobile object servers 220 can smoothly transfer the management of the mobile objects 10 traveling across the regions via the mobile object agents, thereby improving the efficiency of the whole system 100. In addition, according to the system 100 of the embodiment, each event server 210 divides event management in one region among the plurality of event agents and provides the mobile object agent with event information, thereby improving the efficiency of event management in the region (e.g., improving response time of event search) and thus event notification to the mobile objects 10. In addition, the system 100 can provide the mobile object agent with information of mobile object 10 by the object agent of the object server 230. The system 100 can also provide the mobile object agent with information of passengers of the mobile objects 10 by the passenger agent of the passenger server 240.

FIG. 4 shows management of events by the event server 210 and the mobile object server 220, according to an embodiment of the present invention. In this embodiment, a mobile object 10 is traveling on a target route on region A and transmitting a car probe data including the position information to the event server 210 managing region A with the car probe data via a gateway apparatus, such as the gateway apparatus 160. The event server 210 manages event information through each event agent based on the car probe data from the mobile objects on region A. For example, each event agent may manage an event list (containing information of an event and an influence event for routes on the area managed by the event agent) and a candidate event list (containing information of candidates of an event for routes on the area managed by the event agent).

In the embodiment of FIG. 4, the event agent EA2 manages events of an area (indicated as “DA2” on the region A of FIG. 4) by the event list of the event agent EA2 and the candidate event list of the event agent EA2 based on car probe data from the mobile object 10 on the area DA2. For example, the event agent EA2 assigned to the area DA2 is executable to generate an event based on the information from the mobile object 10.

In one embodiment, each mobile object server 220 is operable to receive information from the mobile object 10 in the region A assigned to the mobile object server 220. The mobile object server 220 determines the target route where the mobile object 10 is located. The mobile object server 220 sends the information to one event server 210 assigned to a region A where the mobile object 10 is located, and thereby requests the event agent EA2 assigned to the area DA2 where the target route is located to send an event list containing information of an event on the target route and the influence event of the target route.

The mobile object server 220 executes the mobile object agent MOA1 for the mobile object 10 to provide the mobile object 10 with information that assists the mobile object 10 with traveling in the area DA2 based on the information of the event on the other route and the influence event of the target route. In the embodiment of FIG. 4, the mobile object agent MOA1 receives, from the event agent EA2, the event information of the route on which the mobile object 10 exists, and provides the mobile object 10 with the event information (e.g., information of closure).

FIG. 5 shows management of a mobile object 10 by the mobile object servers 220 and object server 230, according to an embodiment of the present invention. The mobile object server 220-1 may transfer the mobile object agent to the mobile object server 220-2 assigned to a neighboring region in response to the mobile object 10 moving to the neighboring region. In this embodiment, in response to a mobile object 10 traveling from region A to region B, the mobile object server 220-1 managing region A deletes the mobile object agent MOA for the mobile object 10, and a mobile object server 220-2 managing region B generates a mobile object agent MOA for the mobile object 10.

In this embodiment, the object server 230 may store information that includes a mobile object server identifier MOS-ID that identifies one of the plurality of mobile object servers 220 executing the mobile object agent corresponding to the mobile object 10. Just after the mobile object 10 arrives at region B, the mobile object server 220-2 has not been executing the mobile object agent for the mobile object 10. The mobile object server 220-2 is operable to receive information from the mobile object 10 in the region B assigned to the mobile object server 220-2.

Using the information from the mobile object 10, the mobile object server 220-2 obtains the mobile object server identifier MOS-ID from the object server 230 that manages the object agent for the mobile object 10 because the mobile object server 220-2 is not executing the mobile object agent for the mobile object 10. The mobile object server 220-2 requests a mobile object server 220-1 identified by the mobile object server identifier MOS-ID to transfer the mobile object agent for the mobile object 10. Then the mobile object server 220-1 managing region A transfers the mobile object agent to the mobile object server 220-2 assigned to a neighboring region B in response to the request.

FIG. 6 shows an operational flow of a system, according to an embodiment of the present invention. The present embodiment describes an example in which the system 100 performs the operations from S610 to S680 shown in FIG. 6 to manage mobile objects, such as mobile object 10, and events on a map area. FIG. 6 shows one example of the operational flow of the system 100 shown in FIGS. 1-5, but the system 100 shown in FIGS. 1-5 is not limited to using this operational flows explained below. Also, the operational flow in FIG. 6 may be performed by other systems.

First, an acquiring section, such as the acquiring section 110, may acquire the map data of the geographic space to be managed by the system (S610). The acquiring section may acquire map data of a geographic space that includes one or more cities, one or more towns, and the like. The acquiring section may include map data of a geographic space including one or more states, countries, continents, etc. A dividing section, such as the dividing section 130, may divide the map area to generate a plurality of regions.

Next, the system may perform an initialization process for the mobile object (S620). The system may perform the process of S620 if a user (passenger) initializes a setting of a mobile object and any passengers of the mobile object, before starting to drive the mobile object.

After S620, a gateway apparatus, such as the gateway apparatus 160, of the system may acquire a car probe data from the mobile object (S630). Although the system may acquire the car probe data from the plurality of the mobile objects, the system acquiring a car probe data from one mobile object (which, may be referred to as “a target mobile object”) is explained in the below description. The car probe data may include information detected by the target mobile object, such as current position information of the target mobile object, a speed and/or direction of the target mobile object, and event information observed by the target mobile object (e.g., occurrence of ABS, detection of obstacles, or the like). In one embodiment, the position information may include an edge ID of an edge on which the target mobile object exists and the distance between the current location of the target mobile object and the one end of the edge.

Next, the gateway apparatus may determine a region on which the target mobile object is traveling based on the position information of the car probe data of the target mobile object (S640). In one embodiment, the gateway apparatus may inquire a region manager, such as the region manager 140, about the region on which the mobile object exists. A determining section, such as the determining section 146, of the region manager may determine the region the target mobile object and provide the gateway apparatus with the information of the region of the target mobile object. The gateway apparatus may provide an event server, such as the event server 210, that manages the determined region and a mobile object server, such as the mobile object server 220, that manages the determined region with the car probe data.

Next, the event server that is provided with the car probe data of the target mobile object may process events for the mobile objects (S650). The event server may manage event information based on the car probe data for notification of events to the target mobile object.

After S650, the mobile object server that is provided with the car probe data of the target mobile object may manage a mobile object agent for the target mobile object (S660).

After S660, the system determines whether to end the process for the target mobile object. In one embodiment, the gateway apparatus may determine whether the car probe date indicates the engine stop of the target mobile object. If the system determines not to end the process, then the system proceeds with the process of S630 for the target mobile object. If the system determines to end the process, then the system ends the process for the target mobile object, and may continue the process for other mobile objects.

As described above, the system manages mobile objects by utilizing mobile object agents realized by the plurality of the mobile object servers. Since the system can transfer the mobile object agent between the mobile object servers, it can efficiently manage the mobile objects traveling around the plurality of regions. Furthermore, the system collects car probe data from the mobile objects and manages events generated from the car probe data by utilizing the event agents. Since each event server divides a number of events occurring on its managing regions into a plurality of areas by utilizing the event agents, it can efficiently handle event information.

The process of S610 may be performed once before starting processes S620-S680. The process of S620-S680 may be performed for every mobile object.

FIG. 7 shows an operational flow of an initialization process for a mobile object, according to an embodiment of the present invention. The present embodiment describes an example in which the system performs an initialization process, such as the initialization process of S620 of FIG. 6, through processes S621 to S623 shown in FIG. 7.

First, a gateway apparatus receives a setting data (including an ID of the mobile object, an ID(s) of passenger(s) and position information of the mobile object) from the mobile object (S621). The gateway apparatus determines one mobile object server that manages the mobile object based on the position information of the mobile object. The gateway apparatus provides the determined mobile object server with the setting data. Then, the determined mobile object server obtains information (e.g., ID(s) of the passenger(s)) of at least one passenger of the mobile object from the setting data of the mobile object.

Then, the mobile object server may request the object agent of the object server for the mobile object to store the information of the at least one passenger of the mobile object (S622). For example, each mobile object may be mapped to each object agent of the object servers based on values of the IDs of the mobile objects, and the mobile object server may identify one object agent corresponding to the ID of the mobile object based on the calculation using the ID. Then, the mobile object server may provide the object server managing the identified object agent with the setting data including the position information, the ID of the mobile object, and ID(s) of passenger(s) of the mobile object via the gateway apparatus.

Next, the object server stores the information of passenger(s) on an object agent. In one embodiment, each of passengers may be preliminarily mapped to each of the passenger servers based on values of the IDs of passengers, and the passenger servers may have information of passengers. The object server may identify one passenger server corresponding to the ID of a passenger based on the calculation using the ID. The object server may receive, via the gateway apparatus, the information of passengers from the passenger server corresponding to the ID. Then, the object server may store or update the information of the mobile object and the passengers of the mobile object, in the object agent for the mobile object. The object server may include the information of a region that the mobile object currently exists, in the object agent.

Next, the mobile object server 220 managing the region in which the mobile object 10 exists generates a new mobile object agent for the mobile object 10 (S623). In one embodiment, the mobile object server 220 may copy the information of the object agent for the mobile object 10 to the newly generated mobile object agent. For example, the mobile object server 220 may store the information of the mobile object 10 and the information of the at least one passenger of the mobile object 10 in the newly generated mobile object agent for the mobile object 10.

FIG. 8 shows an operational flow of event processing, according to an embodiment of the present invention. The present embodiment describes an example in which the system performs event processing, such as the event processing of S650 of FIG. 6, through processes S651 to S659 shown in FIG. 8.

First, the event server may identify an event agent (S651). In one embodiment, the event sever determines one event agent from the plurality of event agents based on the position information of the target mobile object. The determined event agent may be referred to as “target event agent.” For example, the event server determines a target route (or an edge of the map data) of the target mobile object based on the position information and the map data, and selects, as a target event agent, an event agent that manages an area including the target route of the target mobile object indicated by the car probe data. In another embodiment, the car probe data of a target mobile object may include the information of the target route of the target mobile object.

Next, the event server may edit event lists by the target event agent based on the car probe data (S652). In one embodiment, the target event agent may generate or update information of events (e.g., an edge that an event occurs, an event ID, a location of an event, and content of event) of the target route on the event list based on information of the car probe data. The event of the target route may be referred to as a “target event.”

Next, the event server may search, by the target event agent, an influence event on the target route on the area of the target event agent based on the car probe data (S653). The influence event of the target route relates to an event on another route within a threshold distance (e.g., a threshold travelling distance of the target route, a threshold number of edges away from the target route, and/or a threshold travelling time from the target route).

In one embodiment, the target event agent itself may search routes (or edge IDs) apart from the target route within the threshold distance based on the topology information of routes in the regions, or may request other entities (e.g., a server) to search for routes (or edge IDs).

Next, the event server may determine whether the event list of the target event agent includes event entries corresponding to all influence events of the target route searched at S653 (S654). In one embodiment, the target event agent determines whether edges of the influence events are listed as edge IDs of events in the event list.

If an area managed by a target event agent includes the routes (edges) of all influence events relating to an event, then an event list of the target event agent includes corresponding event entries of all influence events. However, if the routes (edges) of any influence events are managed by other event agents, then the event list may not include corresponding event entries of all influence events. If the decision is positive, then the event server proceeds with the process S655 and if negative, the event server proceeds with the process S656.

At S655, the event server may edit a notification event ID list by the target event agent. The notification event ID list includes IDs of influence events and edge IDs of the influence events that are determined to be not included in the event list of the target event agent at S654. In other words, the notification event ID list is a list of event IDs of influence events that are not managed by the target event agent. Then, the event server may proceed with the process of S656.

At S656, the event server may edit a notification event list for the target mobile object, by the target event agent. The notification event list is a list of events that may be helpful to the target mobile object traveling on the target route. The notification event list may include target events and influence events of the target events. The target event agent may add entries of the target events and the influence events in its managing event list for notification.

Next, the event server determines, by the target event agent, whether the notification event ID list has at least one entry. If the decision is positive, then the event server proceeds with the process of S658, and if negative, then the event server ends the process of S650.

At S658, the event server may identify, by the target event agent, an event agent that manages an event list including events in the notification event ID list. The determined event agent may be referred to as “remote event agent.”

Next, the event server may acquire information of events in the notification event ID list (S659), and end the process S650. In one embodiment, the target event agent may receive information of events in the notification event ID list from the remote event agent, and edit the notification event list based on the acquired information. In another embodiment, the target event agent may add entries of the influence events in the notification event ID list based on the acquired information.

FIG. 9 shows an illustrative example of an event list, according to an embodiment of the present invention. As described in FIG. 9, the event list may include edge IDs of events, event IDs of events, locations of events, specific contents of events, and influence events relating to events. In this embodiment, each route is represented as “edge.” For example, this event list indicates that an event (identified as “Eve 0214”) has occurred along the full length of edge 0001 on the area, that the event has limited the speed to 30 km/h, and that edge 0001 includes an influence event identified as “Eve 0114.” The event list also indicates that an event (identified as “Eve 0114” on edge 0002) has occurred 32 m from the 1st node on edge 0002 on the area, that the event is a closure of a route, and that edge 0001 includes influence events identified as “Eve 0214” on edge 0001, “Eve 0421” on edge 0003, etc. In one embodiment, the target event agent may add a new entry corresponding to an event detected by the car probe data, in the event list.

According to the first entry in the event list of FIG. 9, the edge 0001 has influence event 0114. This may mean that a mobile object traveling on the edge 0001 is influenced by the event 0114 that has occurred apart from edge 0001 within a threshold distance. In response to receiving the car probe data including the position information indicating that the target mobile object is traveling on the edge 0001, the target event agent searches and obtains routes (edge IDs) apart from the target route (edge 0001) within the threshold distance, and then finds neighboring edge 0002 as a result. In response to receiving the car probe data including the position information of the edge 0001, the target event agent determines whether the edge of influence event (edge 0002) corresponding to the target route is listed as edge IDs in the event list.

The target event agent assigned to the area may generate or update a candidate event based on information from the target mobile object. In one embodiment, the target event agent may generate or update candidate events on the candidate event list including information of a plurality of edges on the area of the event agent based on information of the car probe data.

Although the event list of FIG. 9 includes information of influence events, the information of the influence events may be managed by another list. In one embodiment, the event agent may manage both a first event list containing information of an event on the target route and a second event list containing information of the influence event.

FIG. 10 shows an illustrative example of a candidate event list, according to an embodiment of the present invention. As described in FIG. 10, the event list may include edge IDs of candidate events, counts of detecting candidate events, locations of candidate events, and specific contents of candidate events for each candidate event. For example, this candidate event list indicates that evidence of an event (congestion) has been observed twice along the full length of edge 0009 on the area, and that evidence of an event (skid) has been observed once at a point 15 m from the 2nd node on edge 0013 on the area.

The target event agent may determine whether to change a candidate event in the candidate event list to an event in the event list. In one embodiment, the target event agent may upgrade the candidate event to the event based on information from other mobile objects. In this case, the target event agent counts occurrences of a candidate event observed by a plurality of mobile objects (including the target mobile object and other mobile objects). If the count of a candidate event exceeds a threshold value, then the target event agent determines that the candidate event is upgraded to an event. In one embodiment, in response to the upgrade, the target event agent deletes the entry of the candidate event from the candidate event list, and generates a new entry of an event corresponding to the deleted candidate event. The event servers may set the same or different criteria for upgrading candidate events among the plurality of event agents.

FIG. 11 shows an illustrative example of a notification event list, according to an embodiment of the present invention. As described in FIG. 11, the notification event list may include edge IDs of target/influence events, event IDs of target/influence events, locations of target/influence events, and specific contents of target/influence events. For example, this notification event list indicates that an event (speed limit) has occurred along the full length of edge 0001 on the area, and that an event (closure) has occurred at a point 32 m from the 1st node on edge 0002 on the area.

FIG. 12 shows a mobile object and events, according to an embodiment of the present invention. In the embodiment of FIG. 12, the target mobile object 10 is traveling eastbound on the edge 0001, which is the target route. The target event agent EA1 manages an area including the edge 0001, the edge 0002, the edge 0101, and the edge 0102, and the neighboring event agent EA2 manages an area including the edge 0003, the edge 0103, and the edge 0104.

Direction dependent edges are described in FIG. 12. However, edges may not be direction dependent according other embodiments, and in such embodiments, the event agent may manage events, candidate events, and influence events with direction information. The target event agent EA1 manages an event (Eve 0214) on the edge 0001 as the target event in the event list. Since the edge 0002 is apart from the edge 0001 within the threshold distance, the target event agent EA1 also manages an event (Eve 0114) on the edge 0002 as an influence event in the event list. The target event agent EA1 manages a notification event list including the target event (Eve 0214) and the influence event (Eve 0114) for the target mobile object 10.

In the embodiment of FIG. 12, the mobile object agent managing target mobile object requests the event agent EA1 that manages the target event (e.g., Eve 0214) and the influence event (e.g., Eve 0114) to send the notification event list including the target event and the influence event. In another embodiment, the mobile object agent may request the remote event agent EA2 that manages the information of influence event(s) (e.g., Eve 0421) to send a notification event list containing information of the influence event(s) if the influence event is located outside of the area including the target route (Edge 0001).

FIG. 13 shows an operational flow of mobile object processing, according to an embodiment of the present invention. The present embodiment describes an example in which the system manages the target mobile object, such as in S660 of FIG. 6, through processes S661 to S669 shown in FIG. 13.

At S661, the mobile object server may determine whether the mobile object agent for the target mobile object exists in the region determined to be the region of the mobile object, such as the region determined at S640. In other words, the mobile object server determines whether the mobile object server manages the mobile object agent of the target mobile object. If the decision is positive, then the mobile object server proceeds with the process S667, and if negative, the mobile object server proceeds with the process S662.

At S662, the mobile object server may identify an object server that includes the object agent containing the information of the target mobile object. In one embodiment, the mobile object server may identify the object server in the same manner described in S622.

Next, at S663, the mobile object server may inquire the object server 230 identified at S662 for the location of the mobile object agent of the target mobile object. The object server may refer to the object agent of the target mobile object, obtain information of the mobile object server that currently manages the mobile object agent MOA of the target mobile object, if it exists, and provide the mobile object server with the information.

Next, the mobile object server may determine whether the mobile object agent for the target mobile object exists in any other regions. In other words, the mobile object server may determine which mobile object server manages the mobile object agent for the target mobile object from the plurality of mobile object servers managing other regions, at S663. If the decision is positive, then the mobile object server proceeds with the process S666, and if negative the mobile object server proceeds with the process S665.

At S665, the mobile object server generates a new mobile object agent MOA for the target mobile object. The mobile object server may generate the mobile object agent MOA for the target mobile object by obtaining information of the target mobile object from the object server that includes the object agent containing the information of the target mobile object. In one embodiment, the mobile object server may generate the new mobile object agent in the same manner described in S623. The mobile object server may also communicate with the object server via the gateway apparatus, and register the current region of the target mobile object in the object agent corresponding to the target mobile object. By generating the new mobile object agent, the system can handle a new mobile object 10 that has been not managed by the mobile object server.

At S666, the mobile object server may transfer the mobile object agent from the other mobile object server determined to manage the mobile object agent for the target mobile object at 5664. In one embodiment, the mobile object server may receive information of the mobile object agent for the target mobile object from the other mobile object server, and generate a new mobile object agent including the received information. The mobile object server may also communicate with the object server via the gateway apparatus, and register the current region of the target mobile object in the object agent of the target mobile object.

Next, at S667, the mobile object server may receive a notification event list for the target mobile object. In one embodiment, the mobile object server first determines the target route where the target mobile object is located. Then, the mobile object server may request the event agent that manages the information of target event(s) and influence event(s) corresponding to the target route to send a notification event list containing information of the target event(s) and influence event(s) of the target route.

At S668, the mobile object server may update the current location of the target mobile object by the mobile object agent. In one embodiment, the mobile object agent for the target mobile object updates the current location of the target mobile object based on the position information of the car probe data.

At S669, the mobile object server may execute the mobile object agent for the target mobile object to provide the target mobile object with information that assists the target mobile object with traveling in the geographic space based on the information included in the event list. In one embodiment, the mobile object agent may provide the target mobile object with information of events on the notification event list.

In one embodiment, the at least one mobile object server may execute the mobile object agent for the target mobile object to provide the target mobile object with information that assists the target mobile object with traveling in the geographic space based on the information of the at least one passenger of the target mobile object. For example, the mobile object agent may provide the target mobile object with an alert, a notice, and/or an action list relating events on the notification event list depending on a number of passengers (e.g., for guiding a car pool lane), the age, gender, license, real time information (e.g., driving history or sleep history), and characteristics of the passengers.

The action list is a list of actions recommended to passengers in response to the events (e.g., braking, accelerating, and/or steering of the target mobile object).

The action list may include commands to the target mobile object for automatic driving and/or driving assist. In one embodiment, the mobile object agent may include information that the passenger is sensitive to rough driving, and then the mobile object agent may provide commands to gently drive the target mobile object. In one embodiment, the mobile object agent may include information of driving skill of a driver passenger, and then provide different commands depending on the skill of the driver. The mobile object server may provide the target mobile object with the information via the gateway apparatus.

As described above, the mobile object server receives information from the target mobile object in the region assigned to the mobile object server, and generates the mobile object agent for the target mobile object if there is no mobile object server among the plurality of mobile object servers that is executing the mobile object agent.

FIG. 14 shows an exemplary configuration of the system 100, according to an embodiment of the present invention. In this embodiment, each subsystem 200 includes an event server 210, mobile object server 220, an object server 230, and a passenger server 240. However, other embodiments are also possible, in which each subsystem 200 comprises any combination of singles or multiples of each server. In other embodiments, the system 100 may manage allocation of object agents of the object server 230 and passenger agents of the passenger server 240 in the subsystem 200. For example, the gateway apparatus 160 may change allocation of the object/passenger agents to the subsystems 200 to rectify the imbalance of data processing loads among the subsystems 200.

In the embodiment described above, the event server 210 may manage allocated event agents. In other embodiments, the system 100 may manage allocation of event agents to the event servers 210. For example, the gateway apparatus 160 may change allocation of event agents to the event servers 210 to rectify the imbalance of loads of processing events among the event servers 210. In the embodiment described above, the event server 210 causes each event agent to manage allocated divided area derived from a region. In other embodiment, the event server 210 causes at least one event agent to manage specific information regarding events (e.g., cross section of roads or other specific function(s) of a map, or, hurricane or other disaster/accident).

FIG. 15 shows an exemplary configuration of a system 100 according to the present embodiment. In the system 100 according to the present embodiment, components having substantially the same operation as components of the system 100 of the embodiment shown in FIGS. 3 and 14 are given the same reference numerals, and redundant descriptions are omitted. In the present embodiment, the mobile object server 220 may be operable to assist a plurality of mobile objects in a geographic space. The system 100 monitors mobile objects that do not communicate with the system 100, in addition to the plurality of mobile objects.

In the present embodiment, a mobile object that does not communicate with the system 100 is a first mobile object 12. The first mobile object 12 may be a mobile object that does not receive at least some movement assistance from the system 100. The first mobile object 12 is a mobile object that is driven by being manipulated manually by a driver without using the system 100 according to the present embodiment or a mobile object that is managed by a system other than the system 100, for example. The first mobile object 12 may include a mobile object 10 that is managed by the system 100 but is driven manually by a driver. The first mobile object 12 may include a mobile object 10 that is managed by the system 100 but has difficulty communicating with the system 100 due to an irregularity or damage, for example.

In the present embodiment, a mobile object 10 managed by the system 100 is referred to as a second mobile object 10, to be distinguished from a first mobile object 12. In other words, a second mobile object 10 is substantially the same as the mobile objects 10 described in FIGS. 1 to 14, and is a target for assistance by the system 100. In the present embodiment, when not making a particular distinction, the first mobile objects 12 and the second mobile objects 10 are both referred to simply as mobile objects.

At least some of a plurality of second mobile objects 10 may include a sensor or camera for observing the outside, and may be operable to observe other mobile objects using this camera or sensor. In this case, the second mobile object 10 may include the results of observing other mobile objects in the car probe data, and supply this data to the system 100. If a first mobile object 12 is operable to communicate with the system 100, the system 100 may acquire the car probe data from the first mobile object 12. The system 100 may be operable to manage the observation of other mobile objects by supplying signals designating sensitivity, number of frames, angle of field, image quality, observation direction, and the like to the mobile objects that are operable to observe other mobile objects.

The system 100 may be operable to communicate with a monitoring apparatus 50 provided on a route on which the mobile objects move. The system 100 may receive results of observing mobile objects moving on the route from the monitoring apparatus 50. The system 100 may be operable to receive the results of observing the mobile objects along with position information of the monitoring apparatus 50. The system 100 may be operable to supply the monitoring apparatus 50 with a signal designating sensitivity, number of frames, angle of field, image quality, observation direction, and the like, to manage the observation of the mobile objects by the monitoring apparatus 50. Some or all of the monitoring apparatus 50 may be a portion of the system 100.

The subsystems 200 according to the present embodiment may manage the second mobile objects 10 while monitoring the first mobile objects 12 in a geographic space being managed. In the present embodiment, the mobile object server 220 in each subsystem 200 further includes a receiving section 310, a monitoring section 320, an observation instructing section 330, a history storage section 340, a movement predicting section 350, and an assisting section 360.

The receiving section 310 may be operable to receive information of other mobile objects observed by at least one of a second mobile object 10 and the monitoring apparatus 50. The receiving section 310 may receive the mobile object observation results as car probe data from second mobile objects 10 that are capable of observing other mobile objects. If the receiving section 310 receives mobile object information from the monitoring apparatus 50, the system 100 may supply the subsystem 200 corresponding to the position information of the monitoring apparatus 50 with the mobile object information received from the monitoring apparatus 50, in the same manner as the car probe data.

The monitoring section 320 may be operable to monitor the first mobile objects 12. The monitoring section 320 may be operable to monitor the first mobile objects 12 using the received information from the first mobile objects 12. The monitoring section 320 may be operable to observe first mobile objects 12 that are driven manually and first mobile objects 12 that are driven automatically but do not receive assistance from this system 100, for example. The monitoring section 320 may detect a first mobile object 12 by comparing mobile object information observed by the monitoring apparatus 50 and/or a second mobile object 10 to information of a second mobile object 10 managed by the mobile object server 220, and monitor the movement of the detected first mobile object 12.

The observation instructing section 330 may be operable to instruct a second mobile object 10 positioned within a predetermined range from a first mobile object 12 to observe this first mobile object 12. If a first mobile object 12 is detected, the observation instructing section 330 may instruct a second mobile object 10 capable of observing mobile objects, from among the second mobile objects 10 moving near this first mobile object 12, to observe this first mobile object 12. In this case, the observation instructing section 330 may instruct the mobile object agent MOA corresponding to this second mobile object 10 to observe the first mobile object 12.

The history storage section 340 may be operable to store history information of first mobile objects 12 that are monitoring targets. The history storage section 340 may store results obtained by the monitoring section 320 detecting and monitoring the first mobile objects 12 as the history information. The history storage section 340 may further store information concerning the routes on which second mobile objects 10 move and/or statistical information concerning the routes on which the second mobile objects 10 move, as the history information.

The movement predicting section 350 may be operable to predict a destination of a first mobile object 12. The movement predicting section 350 may predict the movement destination of the first mobile object using the results obtained from monitoring the first mobile object 12. The movement predicting section 350 may predict the movement destination of the first mobile object 12 based on the history information of the first mobile object 12 stored in the history storage section 340. The movement predicting section 350 may predict the movement destination of the first mobile object 12 based on the history information of the second mobile objects 10 stored in the history storage section 340.

The assisting section 360 may be operable to assist with the movement of the second mobile objects 10 using the results obtained by monitoring the first mobile object 12. The assisting section 360 may be operable to assist with the automatic driving of the second mobile objects 10. The assisting section 360 may be operable to assist with the movement of the second mobile objects 10 using the history information of the first mobile object 12 stored in the history storage section 340. The assisting section 360 may be operable to assist with the movement of the second mobile objects 10 using the prediction results of the movement predicting section 350.

The assisting section 360 may be operable to notify a second mobile object 10 about the information of a first mobile object 12 positioned within a reference range from the second mobile object 10. The assisting section 360 may be operable to notify a second mobile object 10 positioned within a reference range from a position predicted as the movement destination of the first mobile object 12 about the information of this first mobile object 12. The assisting section 360 may transmit to the mobile object agent MOA corresponding to a second mobile object 10 notification and/or instructions corresponding to the information of the first mobile object 12.

The system 100 according to the present embodiment described above detects and monitors a first mobile object 12 based on mobile object information observed by the monitoring apparatus 50 and/or a second mobile object 10, and manages the second mobile objects 10 according to the monitoring results. The operation of managing the second mobile objects 10 performed by this system 100 is described below.

FIG. 16 shows an exemplary configuration of a portion of the operational flow of the system 100 according to the present embodiment. The mobile object server 220 according to the present embodiment may be operable to assist with the movement of a plurality of second mobile objects 10 within a geographic space, by performing the operational flow shown in FIG. 16. Specifically, the operational flow of FIG. 16 may be performed by the mobile object server 220 in addition to or instead of the processing at S660 (Mobile Object Server Processing) of the mobile object server described in FIGS. 6 and 13.

First, at S671, the receiving section 310 may receive information of another mobile object observed by at least one of the monitoring apparatus 50 and a second mobile object 10. The receiving section 310 may supply the monitoring section 320 with the information of this other mobile object.

At S672, the monitoring section 320 may judge whether the other mobile object is a first mobile object 12. The monitoring section 320 may be operable to begin monitoring this other mobile object as a new first mobile object 12 in response to this other mobile object observed by the monitoring apparatus 50 and/or a second mobile object 10 not matching any second mobile object 10 that is an assistance target. For example, the monitoring section 320 makes this judgment by detecting the presence of information substantially matching the positional information, outer appearance, passenger characteristics (number or genders of the passengers), and the like among the information of the plurality of mobile object agents managed by the mobile object server 220.

If there is information that matches the information of this other mobile object, the monitoring section 320 may judge that this other mobile object is a second mobile object 10. If no other first mobile object 12 to be monitored is detected (S672: No), the monitoring section 320 may end this operation. If there is no information matching the information of this other mobile object, the monitoring section 320 may judge that this other mobile object is a first mobile object 12 (S672: Yes) and begin monitoring this first mobile object 12.

At S673, the observation instructing section 330 may instruct a second mobile object 10 moving near this first mobile object 12 to observe the first mobile object 12. If there is another monitoring apparatus 50 positioned within a predetermined range from this first mobile object 12, the observation instructing section 330 may instruct this other monitoring apparatus 50 to observe the first mobile object 12.

If a second mobile object 10 and/or a monitoring apparatus 50 is instructed to observe the first mobile object 12, the observation instructing section 330 may further designate sensitivity, number of frames, angle of field, image quality, monitoring direction, and the like for the observation by the second mobile object 10 and/or monitoring apparatus 50. In this way, the monitoring section 320 can improve the accuracy of the monitoring of the first mobile object 12 and continue this monitoring.

At S674, the monitoring section 320 may store the results obtained by monitoring the first mobile object 12 that is the monitoring target in the history storage section 340. If a plurality of first mobile objects 12 are being monitored, the monitoring section 320 may accumulate the monitoring results for each first mobile object 12.

At S675, the movement predicting section 350 may predict the movement destination of the first mobile object 12. If a history of detection of the first mobile object 12 in the past at the position of the first mobile object 12 is stored, the movement predicting section 350 may set the direction in which the first mobile object 12 moved in this history to be the predicted direction of the first mobile object 12 being currently monitored.

If a history of movement of a second mobile object 10 in the past at the position of the first mobile object 12 is stored, the movement predicting section 350 may set the direction in which this second mobile object 10 moved to be the predicted direction of the first mobile object 12 being currently monitored. Furthermore, if histories of movement of a plurality of mobile objects at the position of the first mobile object 12 are stored, the movement predicting section 350 may predict the movement destination of the first mobile object 12 being currently monitored based on the statistical information of these histories.

At S676, the assisting section 360 may assist with the movement of the second mobile object 10 that is an assistance target based on the results of monitoring the first mobile object 12. The assisting section 360 may be operable to assist with the movement of the second mobile object 10 using at least one of an outer appearance of the observed first mobile object 12, a driving characteristic, a characteristic of a passenger, and a characteristic of a route on which the first mobile object 12 is positioned.

The assisting section 360 may be operable to instruct the second mobile object 10 in a manner to be distanced from the first mobile object 12 by at least a reference distance. The assisting section 360 may be operable to guide the second mobile object 10 into a route differing from the route on which the first mobile object 12 is moving. If there is a second mobile object 10 within a reference range from the position of the first mobile object 12, the assisting section 360 may instruct this second mobile object 10 to move outside of this reference range.

The assisting section 360 may determine whether to avoid the first mobile object 12 according to the outer appearance of the first mobile object 12, such as scratches, the state (peeling paint or rust), and alterations. The assisting section 360 may determine whether to avoid the first mobile object 12 according to fluctuation in the distance between the first mobile object 12 and the second mobile object 10. If it is determined that the first mobile object 12 is to be avoided, the assisting section 360 may instruct a second mobile object 10 in the same lane as this first mobile object 12 to make a lane change. If it is determined that the first mobile object 12 is to be avoided, the assisting section 360 may instruct a second mobile object 10 on the same route as this first mobile object 12 to change routes.

The assisting section 360 may assist with the movement of a second mobile object 10 using the movement destination of the first mobile object 12 predicted by the movement predicting section 350. For example, the assisting section 360 instructs the second mobile object 10 to be at a distance greater than or equal to a reference distance from the predicted position where the first mobile object 12 will move. The assisting section 360 may instruct the second mobile object 10 to change routes to be on a route differing from the route on which the first mobile object 12 is predicted to move.

In the manner described above, if a first mobile object 12 moves into a geographic space being managed, the mobile object server 220 can manage the movement of a plurality of second mobile objects 10 while monitoring the movement of this first mobile object 12. In other words, the system 100 can assist with the automatic driving of a plurality of second mobile objects 10 by monitoring a first mobile object 12 that is driven manually or a first mobile object 12 that is driven automatically without receiving assistance from this system 100. In this way, the system 100 manages the movement of the second mobile object 10 according to the results obtained by monitoring an automobile whose behavior is difficult to predict, for example, and can therefore reduce the risk of dangerous driving, accidents, and the like.

The system 100 according to the present embodiment described above assists with the automatic driving of a plurality of second mobile objects 10, based on results of monitoring a first mobile object 12. Instead of or in addition to this, the system 100 may be operable to process movement of a first mobile object 12 as an event. For example, the monitoring section 320 notifies as event server 210 that is operable to process events occurring in the geographic space about information of the first mobile object 12. In this case, the event server 210 may be operable to register the presence of the first mobile object 12 as an event. The assisting section 360 may be operable to assist with movement of the second mobile objects 10 based on the events registered in the event server 210. For example, the assisting section 360 may assist with the movement of the second mobile objects 10 according to the event of a first mobile object 12 received from the event server 210.

The system 100 according to the present embodiment described above monitors the first mobile object 12 using the mobile object server 220. In addition to this, the mobile object server 220 may assign a traced mobile object agent TMOA to correspond to a first mobile object 12 to be monitored, and perform monitoring using this traced mobile object agent TMOA.

Specifically, the mobile object server 220 may assign a traced mobile object agent TMOA in response to detection of a first mobile object 12, and update the information of the traced mobile object agent TMOA according to the results obtained by monitoring the first mobile object 12. If an assigned traced mobile object agent TMOA does not observe anything for longer than a reference time period, the mobile object server 220 may remove this traced mobile object agent TMOA. In this way, the mobile object server 220 can easily manage the monitoring results of the movement of a plurality of first mobile objects 12 for each first mobile object 12, by using the traced mobile object agents TMOA.

If the monitoring results for a first mobile object 12 are being managed using a traced mobile object agent TMOA, the system 100 may perform management using a server other than the mobile object server 220. For example, the system 100 may include a traced mobile object server for each subsystem 200. Such a system 100 is shown in FIG. 17.

FIG. 17 shows an exemplary configuration of a system 100 according to the present embodiment. The subsystem 200 further includes a traced mobile object server 300. The traced mobile object server 300 includes a receiving section 310, a monitoring section 320, an observation instructing section 330, a history storage section 340, a movement predicting section 350, and an assisting section 360. In the system 100 of the present embodiment, components having substantially the same operation as components of the system 100 of the embodiment shown in FIG. 15 are given the same reference numerals, and redundant descriptions are omitted.

The system 100 according to the present embodiment shown in FIG. 17 may be operable to perform the monitoring of a first mobile object 12 described in FIGS. 15 and 16 using a traced mobile object server 300 that is different from the mobile object server 220. Furthermore, the traced mobile object server 300 may be operable to manage the monitoring results of the first mobile object 12 using a traced mobile object agent TMOA. The traced mobile object server 300 may transmit instructions for assisting the second mobile objects 10 to the mobile object server 220, according to information concerning detection, movement, and predicted movement from the traced mobile object agent TMOA. The traced mobile object server 300 may register the information from the traced mobile object agent TMOA in the event server 210.

FIG. 18 shows an exemplary configuration of a computer 1900 according to an embodiment of the invention. The computer 1900 according to the present embodiment includes a CPU 2000, a RAM 2020, a graphics controller 2075, and a display apparatus 2080 which are mutually connected by a host controller 2082. The computer 1900 also includes input/output units such as a communication interface 2030, a hard disk drive 2040, and a DVD-ROM drive 2060 which are connected to the host controller 2082 via an input/output controller 2084. The computer also includes legacy input/output units such as a ROM 2010 and a keyboard 2050 which are connected to the input/output controller 2084 through an input/output chip 2070.

The host controller 2082 connects the RAM 2020 with the CPU 2000 and the graphics controller 2075 which access the RAM 2020 at a high transfer rate. The CPU 2000 operates according to programs stored in the ROM 2010 and the RAM 2020, thereby controlling each unit. The graphics controller 2075 obtains image data generated by the CPU 2000 on a frame buffer or the like provided in the RAM 2020, and causes the image data to be displayed on the display apparatus 2080. Alternatively, the graphics controller 2075 may contain therein a frame buffer or the like for storing image data generated by the CPU 2000.

The input/output controller 2084 connects the host controller 2082 with the communication interface 2030, the hard disk drive 2040, and the DVD-ROM drive 2060, which are relatively high-speed input/output units. The communication interface 2030 communicates with other electronic devices via a network. The hard disk drive 2040 stores programs and data used by the CPU 2000 within the computer 1900. The DVD-ROM drive 2060 reads the programs or the data from the DVD-ROM 2095, and provides the hard disk drive 2040 with the programs or the data via the RAM 2020.

The ROM 2010 and the keyboard 2050 and the input/output chip 2070, which are relatively low-speed input/output units, are connected to the input/output controller 2084. The ROM 2010 stores therein a boot program or the like executed by the computer 1900 at the time of activation, a program depending on the hardware of the computer 1900. The keyboard 2050 inputs text data or commands from a user, and may provide the hard disk drive 2040 with the text data or the commands via the RAM 2020. The input/output chip 2070 connects a keyboard 2050 to an input/output controller 2084, and may connect various input/output units via a parallel port, a serial port, a keyboard port, a mouse port, and the like to the input/output controller 2084.

A program to be stored on the hard disk drive 2040 via the RAM 2020 is provided by a recording medium as the DVD-ROM 2095, and an IC card. The program is read from the recording medium, installed into the hard disk drive 2040 within the computer 1900 via the RAM 2020, and executed in the CPU 2000.

A program that is installed in the computer 1900 and causes the computer 1900 to function as an apparatus, such as the region manager, the subsystems 200 and other element(s) in the system 100 of FIG. 3, FIG. 14, FIG. 15, and FIG. 17, includes a determining module. The program or module acts on the CPU 2000, to cause the computer 1900 to function as a section, component, element such as determining section 146.

The information processing described in these programs is read into the computer 1900, to function as the determining section, which is the result of cooperation between the program or module and the above-mentioned various types of hardware resources. Moreover, the apparatus is constituted by realizing the operation or processing of information in accordance with the usage of the computer 1900.

For example when communication is performed between the computer 1900 and an external device, the CPU 2000 may execute a communication program loaded onto the RAM 2020, to instruct communication processing to a communication interface 2030, based on the processing described in the communication program. The communication interface 2030, under control of the CPU 2000, reads the transmission data stored on the transmission buffering region provided in the recording medium, such as a RAM 2020, a hard disk drive 2040, or a DVD-ROM 2095, and transmits the read transmission data to a network, or writes reception data received from a network to a reception buffering region or the like provided on the recording medium. In this way, the communication interface 2030 may exchange transmission/reception data with the recording medium by a DMA (direct memory access) method, or by a configuration that the CPU 2000 reads the data from the recording medium or the communication interface 2030 of a transfer destination, to write the data into the communication interface 2030 or the recording medium of the transfer destination, so as to transfer the transmission/reception data.

In addition, the CPU 2000 may cause all or a necessary portion of the file of the database to be read into the RAM 2020 such as by DMA transfer, the file or the database having been stored in an external recording medium such as the hard disk drive 2040, the DVD-ROM drive 2060 (DVD-ROM 2095) to perform various types of processing onto the data on the RAM 2020. The CPU 2000 may then write back the processed data to the external recording medium by means of a DMA transfer method or the like. In such processing, the RAM 2020 can be considered to temporarily store the contents of the external recording medium, and so the RAM 2020, the external recording apparatus, and the like are collectively referred to as a memory, a storage section, a recording medium, a computer readable medium, etc. Various types of information, such as various types of programs, data, tables, and databases, may be stored in the recording apparatus, to undergo information processing. Note that the CPU 2000 may also use a part of the RAM 2020 to perform reading/writing thereto on the cache memory. In such an embodiment, the cache is considered to be contained in the RAM 2020, the memory, and/or the recording medium unless noted otherwise, since the cache memory performs part of the function of the RAM 2020.

The CPU 2000 may perform various types of processing, onto the data read from the RAM 2020, which includes various types of operations, processing of information, condition judging, search/replace of information, etc., as described in the present embodiment and designated by an instruction sequence of programs, and writes the result back to the RAM 2020. For example, when performing condition judging, the CPU 2000 may judge whether each type of variable shown in the present embodiment is larger, smaller, no smaller than, no greater than, or equal to the other variable or constant, and when the condition judging results in the affirmative (or in the negative), the process branches to a different instruction sequence, or calls a sub routine.

In addition, the CPU 2000 may search for information in a file, a database, etc., in the recording medium. For example, when a plurality of entries, each having an attribute value of a first attribute is associated with an attribute value of a second attribute, are stored in a recording apparatus, the CPU 2000 may search for an entry matching the condition whose attribute value of the first attribute is designated, from among the plurality of entries stored in the recording medium, and reads the attribute value of the second attribute stored in the entry, thereby obtaining the attribute value of the second attribute associated with the first attribute satisfying the predetermined condition.

The above-explained program or module may be stored in an external recording medium. Exemplary recording mediums include a DVD-ROM 2095, as well as an optical recording medium such as a Blu-ray Disk or a CD, a magneto-optic recording medium such as a MO, a tape medium, and a semiconductor memory such as an IC card. In addition, a recording medium such as a hard disk or a RAM provided in a server system connected to a dedicated communication network or the Internet can be used as a recording medium, thereby providing the program to the computer 1900 via the network.

The present invention may be a system, a method, and/or a computer program product. The computer program product may include a computer readable storage medium (or media) having computer readable program instructions thereon for causing a processor to carry out aspects of the present invention.
